Hi everyone. Haven't managed to get on recently. We've had a painter in the house last week and this week, my family have been visiting and my lovely DD hasn't been sleeping at all well.
We had a Skype with Robin just over a week ago and it went really well. He was pleased with our progress and the improvements in DS. We're now doing the Richard Scarry book as well as stairs and chair. He quite likes doing the hemi P. I described it as doing work on the computer like Mummy Pig does in a peppa episode and that seems to have stuck! He's still improving but it's baby steps, and like you all said, it's creeping up on me rather than being huge changes from day to day. His nursery place has been confirmed for August so I feel like I'm working towards that too.
prince - I'm glad your lunch date with friends went well. We haven't had any of those kind of problems with people we know, but I do notice the differences between DS and his friends when we meet up. I'm convinced when his language comes on a bit more he'll start to interact more with other children. DH and I think he's doing great and celebrate new things he does, then I realise that most parents don't celebrate the small stuff as they don't have to work for it like we do. Having DD also shows us the stuff DS didn't do. She's just started picking up something like a brick and pretending to eat it. Then she'll offer it to us to try. It's very cute but I now know he didn't do that. I feel like the innocence has gone as I'm kind of waiting to tick off all her milestone developments. 
Your DD sounds like she's doing really well! You must be so thrilled! Wrt to the exercises, and it might not work for you, but I try and do things like getting DS to do a spinning chair with his favourite toy before he does his go. Or (very occasionally) he does a spinning chair with me first then he has his turn, but it totally makes me want to vomit and he doesn't spin it very quickly at all! Just helps to keep it a bit more fun and less like a chore. Would that help?
ruggles you sound like you have similar problems with your mum as we have with my Mil and Fil. They love DS so much and think he's so perfect, and therefore can't see that anything could be wrong with him. They make excuses for the stuff he isn't doing that he should be, like having a conversation with them, and make his 'quirks' into 'normal' behaviours. I find it quite tiring.
badvoc don't wobble! You all picked me up when I wobbled a few weeks back and you were right. You and Tom have come so much further than us so think of where you started and the amazing progress he has made. You can see the light at the end of the tunnel now. You're so nearly there! Chin up for the last bit! 
And I'm thrilled for you that he loved his trip away!
harriet I'm interested in your pancake recipe... Was it just a normal pancake batter but with an extra egg and a banana? Was that the large, thin type of pancake, or more your thicker drop scone type? I'm always on the lookout for new protein breakfast options for my egg refusing son.
Fingers crossed for an improvement in the weather. We had hailstones today though we are in Scotland!!!
